I am currently taking tutorials on how to use CodeIgniter and am taking a tutorial to create a simple newsletter. For some reason when I hit the submit button a 404 page not found error is created and its obvious because the url doubles. Meaning, the url is:
www.my_site.dev/index.php/email
and when I hit the submit button is should be:
www.my_site.dev/index.php/email/send
but it doubles the url like this:
www.my_site.dev/index.php/www.my_site.dev/index.php/email/send
I am using the form helper:
$autoload['helper'] = array('url', 'form');
I just can't figure out where in the autoload or config files how to troubleshoot the reason for this or what to set to make the action appropriate.
To clear up any confusion HERE is my view and controller.
Adding http:// to base_url is a start, but is base_url set to http://example.com/ or http://example.com/index.php ? (the latter one is incorrect)

In a plain Play application I have the following scenario.
A route file which looks like this:
GET /accounts/add controllers.Accounts.add()
POST /accounts controllers.Accounts.create()
The first route results in a view where I can add a new account. The form to submit the new account looks something like this:
#helper.form(action = routes.Accounts.create()) {...}
Now the controller binds the input to the form and checks for any validation errors:
public static Result create() {
Form<Account> form = Form.form(Account.class).bindFromRequest();
if (form.hasErrors()) {
return badRequest(views.html.account.add.render(form));
}
...
}
Now the thing is, the client will see the same view with some additional error messages. However, meanwhile the URL has changed from http://example.com/accounts/add to http://example.com/accounts.
If the client now reloads the browser this calls GET http://example.com/accounts (which isn't even mapped in this scenario - thus getting a 404 - Not Found).
Maybe it's just me but I find this kind of annoying and browsing some GitHub projects I couldn't find a good solution for this case.
Of cause things would be much simpler if the second route is rewritten to:
POST /accounts/add controllers.Accounts.create()
... in which case everything works fine. But from a REST point of view this doesn't feel good either. The same applies to update scenarios (having GET /accounts/:id/update vs. PUT /accounts/:id).
Is there a guide on how to handle this? Am I getting something wrong or is this no problem at all (from a pragmatic point of view)?
It's not possible to leave the previous URL because a request for a new address has already been made. A controller only provides response for a requested resource. To go to the previous URL you could only make a redirect in case of validation failure but you would lost errors that way so this is not a solution.
I suggest mapping both actions with the same URL. This way you would solve problem with the browser reload.
If you create a REST service for http clients that aren't browsers you will probably want to serve different response than a simple http page. The separation of actions for particular clients could be a good solution for keeping REST API clean and a browser user happy.
In Drupal 7, some of (non-existing) URLs are not redirecting to 404 or any error page it should. Instead, it still remains showing its Top Parent Folder. For example like:
www.mywebsite.com/items/aaaaaaaaaaaaa
www.mywebsite.com/items/bbbbbbbbbbbbbbbbbb
Every WRONG URLs under /items/ i put like above, are showing the Page of its parent:
www.mywebsite.com/items instead of get redirected to 404
I don't want its parent to be shown if there is no page really.
But the strange thing is, it is NOT happening on every patterns. I mean, another different parents like:
www.mywebsite.com/users/aaaaaaaaaaaaa
www.mywebsite.com/users/bbbbbbbbbbbbbbbbb
For the wrong url typed-in under this /users/ parent path, it is CORRECTLY redirecting to the 404 page.
What is it please?
If I understand your question correctly, it's not a problem at all.
That's because how your/contributed/core modules hooks Drupal menu system.
If a menu item (menu router item to be specific. Think about a path like "admin/config/development/performance") has no "%" sign in it, menu callback function will be executed.
For an example, if a module registers "items" path example.com/items path would not be a 404, and the appropriate menu callback function of the menu item will be fired. That callback function can make use of further URL parts (example.com/items/123) if given.
'node' is a good example. (technically they are different menu router items though) .
Opening example.com/node will not fire a 404.
If a module registers 'items/%' , then, example.com/items will fire a 404. In other words, the second URL part is required in order to execute the menu callback function.
If the problem you are facing is related to a custom module, make sure you register the correct version of your router items. If the second URL part is required, register items/%.
You can execute a 404 by calling drupal_not_found().
Look at this, really helpfull
http://peterpetrik.com/blog/2009/11/non-existent-urls-views-2
Are you using Views for that path (/items)?
Here is an issue for Views: Prevent duplicate content (because Views returns 200 instead of 400 404)
You could create a Contextual filter to prevent this.

If you don't want this behavior, add the Global: NULL argument to Views and use the setting to validate that the argument is empty.
For Drupal 6, the module Views 404 might help.
You can configure your drupal installation to redirect to a specefic 404 page that you create..
Go to www.yoursite.com/admin/config/system/site-information and enter your 404 page .
first post in SO, even though I've been browsing it for years now to solve those mind-blowing and not so much coding problems.
What I want to do is:
* Use hash navigation (#!/).
* Use Zend controller actions, not php files.
* Load these actions through javascript/jQuery.
So far, I've got this working:
indexController, several Actions, each attached to AjaxContext via addActionContext(), I can call them though my javascript/jQuery file via "hashchange" plugin jQuery(window).hashchange(function(){ bla bla }). I can cycle through actions just fine.
But I want to redirect the user to a login page if he/she is not logged in, which brings me to my issue: How can I achieve that? The redirection is made to another controller (login controller, login action). I was trying something like $this->_redirect('/#!/login/login'); w/o any luck (yes, I've set up an AjaxContext in that controller's init). I keep getting a redirection error ("The page isn't redirecting properly"). If I just type in the address bar "/#!/login/login" I get everything display properly.
Anyway, thanks in advance!
Cheers
Now this starts to get complicated if you ever introduce other non-ajax contexts, but you could add the Ajax context to the Error Controller. Then have the error controller return JSON for the unauthenticated exception if the active context was AJAX (and keep the redirect if the default context was active). Your JS would then listen for that specific error provided by the JSON and manually bounce the user to the appropriate login URL.
I have these URLs
cz/kontroler/akce
en/controller/action
Is used transatable route and works it like charm. But problem is, that when you will write
cz/controller/akce
it works as well.
In generally when you have
cz/something-in-czech
en/something-in-english
which route to someController, will be works still
cz/some
en/some
because it is really name of controller.
How solve this duplicity content issue?
You can create a plugin that uses a preDispatch method. Before the request is executed, you can analyze the url requested and check if the requested language match the language of the params in the url (I mean controller and action). If not, you can redirect the user to the url that is in accord to the given language (basically you'll translate the controller and the action and then redirect the user to the right url).
I am using T4MVC to redirect to another action return RedirectToAction(MVC.MyController.MyAction());.
In result it is doing get request.
Is there any way to make post request from controller. I want to keep all the same but only make post instead get. I cant find any methods for that. I found one post helper here http://geekswithblogs.net/rakker/archive/2006/04/21/76044.aspx but i cant pass any values i need using this post helper. I was trying to pass values through TempData but they are not coming when i using this helper. May be some one have any ideas?
The reason i want to do this because when user come from one controller to another and then if user click update or just click enter in browser address bar, page will break.
Should i use session for that reason?
A RedirectToAction will always perform a GET, never a POST (it returns a HTTP 302 to the browser, which will then issue a GET request).
To persist data across the redirect, if it is data that can be easily represented as a string and stored in the query string, then you can just add it to the route values of the redirect.
e.g.
return RedirectToAction("Search", new { searchString = "whatever" });
If it is a complex type, then you will need to store it in TempData. A number of other questions on StackOverflow (such as this one) give details on how.
If repeatedly storing to and reading from TempData across your application offends your code-sense, then you can encapsulate this by using the PassParametersDuringRedirect attribute and generic RedirectToAction available in the MvcContrib project. Some details on this technique are available here.
only way of doing post is by having a form and doing submit on that form, either with a submit button or with javascript, any info you want passed to that action must be in that form and you will find everything posted in FormCollection(hope I spelled it right).
